AUGUST WV. KIENTOFF, OF DALLAS, OREGON.

CH RONOMETER-ESCAPEM ENT.

SPECIFICATION forming part of Letters Patent No. 283,349, dated'August14, 1883.

Application filed October 1, 1881. (ModeL) To all whom it may concern:

Be it known that I, AUGUST WV. KIENTOFF, of Dallas, in the county ofPolk and State of Oregon, have made certain new and useful Improvementsin Ohronometer-Escapement, of which the following is a full, clear, andexact description, reference being had to the accompanying drawings andletters of reference marked thereon, in which Y Figure 1 is a top Viewof my improved chronometer-escapement. Fig. 2 is a top view of the lowerplate, showing the escapementwheel locked. Fig. 3 is a View partly insection, and Fig. 4 is a detail side elevation of the eseapement partlyin section.

My invention relates to improvements in chronometer-escapement; and itconsists in the peculiar construction and arrangement of the parts, ashereinafter more fully set forth,

and pointed out in the claims.

In the accompanying drawings, a a. represent two plates connectedtogether by the posts I).

0 represents a shaft journaled in the plates a a and carrying theclock-wheel d, which meshes with the lantern-wheel e or a pinion on theshaft f, journaled in the plates a a, which shaft f also carries theescapement-wheel 71, toothed in the usual manner.

i represents the balance-staff, journaled at its lower end in the lowerplate a, and journaled at its upper end ina bridge, g, secured to theupper plate a and projecting over it, the upper plate a being out out toallow the passage of the balance-staff and other devices, hereinafterdescribed. The balance-wheel k is secured to the balance-staff i nearits upper end.

Z represents a lug or disk secured to the balance-staff i, and carryinga roller or pin, m, projecting downward, so as to engage with theescapement-wheel h.

n represents a shaft journaled at its lower end in the plate a, to theupper end of which is secured an oscillating lever, 0, cut out near itsmiddle for the passage of the balance-staff i.

.p p represent banking-pieces secured to the upper plate a, near theopening therein, on each side of the free end of the oscillating levero, by setscrews inserted in slots in the bankingpieces, whereby thelatter are adjustable to and from the oscillating lever o, thebankingpieces 1) acting as stops for the oscillating lever 0.

1 represents a coiled spring, one end of which is secured to thebalance-staff z, the op posite end passing through a lug on the outerend of the oscillating lever o.

r representsa frame adjustably secured to the upper face of thebottomplate a, and provided with a cross-bar, s, journaled in the sidesof the frame, to which cross-bar s is secured a vertical locking-lever,t, to the upper arm of which the spring a is secured at its lower end tothe locking-lever, lying along and in contact with said locking-leverand projecting slightly above it at its upper end. The upper end of thelocking-lever lies in the path of the oscillating lever 0, and its lowerend, when thrown inward, engages with a tooth of the escapement-wheeland holds it locked.

o represents a stud secured to the upper face of the lower plate a, andprovided with a spring, '10, the free inner end of which presses againstthe upper arm of the locking-lever i, so as to throw inward the lowerarm of the lockinglever and lock the escapement-wheel. Motion beingimparted to the balance-wheel, the lever o is oscillated by means of thecoiled spring q, and, striking the lever 15, the latter is unlocked fromthe escapement-wheel, a tooth of the latter striking the roller m, whichmoves the balance-staff and balance-wheel, the spring 10 throwing thelever i into lock with the escapement-wheel after it has moved the distanceof one tooth.

Having thus fully described my invention,

-what I claim as new, and desire to secure by Letters Patent, isp 1. Thecombination, with the escapementwheel h, of the balance-staff z,carrying the balance-wheel Ia and roller m, spring q, oscillating ,lever0, and locking-lever t, substantially as described, and for the purposeset forth.

2. The combination, with the escapement wheel 71, balance-staff i,roller m, spring q, and oscillating lever o, of the frame r, cross-bars, locking-lever t, and springs a 20, substantially as described, andfor the purpose set forth.

AUGUST WV. KIENTOFF.
